y ATTACHMENT FOR CUPOLA-FURNACES FOR RECEIVING THE DUMP.

SPECIFICATION forming part of Letters'latent No. 287,527, dated October 30, 1883.

Y I Application filed May 7, 1883. (No model.) 4 I To all whom it may concern:

Beit known that I, HENRY W. FAYETTE, of the city, county, and State of New York, have invented certain new and useful Improve- 5 ments'in Attachments or Devices for Cupola- Furnaces for Separating the Iron from the Debris or Dump, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My improvement relates especially to cupola-furnaces, and has for its object the production of a device simple and effective in operation, and whereby much of the metal heretofore wasted and lost after each heat will be reclaimed by the expenditure of little time l and trouble. K

To attain this end my invention consists, essentially, in a pit beneath the furnace, having a sloping floor terminating at one side in ingot-molds or a space wherein pigs may be formed. A track is laid under the furnace be: tween the supporting Vpillows or walls. Upon this track, running upon suitable wheels, is located a cone-shaped grate, the center or apex whereof` is near the center of the -furnace. The bars of the grate are provided with projecting points or spurs. Beneath the taphole of the furnace is located a grate, upon which the ladles are supported while being filled. Beneath said grate a channel leads to the molds above mentioned. By this means any'metal accidentally spilled while filling aladle will be caught and conveyed to the rmolds. y

` In furnaces lof this character as heretofore constructed, it has been customary after each heat to drop the doors at the bottom of the furnace and dump the refuse matterinto the pit there beneath. By so doing a quantity of metal or shot-iron7 aggregating several hundred pounds was lost, or, if reclaimed, entailing an outlay of labor not warranted by the value of the metal, the iron taken from the dum'p being in such small pieces ask to greatly retard the heat whereinV it was remelted. By my device this loss and extra labor and expense is overcome, as when the doors are released the 'mass supported thereon 5o' falls, the sand floor forming the foundation of the charge first strikes the cone-shaped grate,

-metal in anyV approved manner.

y run into pigs instead of igots.

and the mass, being semi-fluid, catches upon the spurs, bending downward in each direction, allowing the molten metal to flow down through the grate-bars over the inclined floor f to the molds prepared for its reception at the side or back of the furnace. When the dump is sufficiently drained, the grate is drawn out from under the furnace upon its supportingtrack and the refuse matter removed.

In the drawings, Figure 1 is a vertical central sectional view of a 'cupola with which my improvement is employed. Fig. 2 is a plan view of the cone-shaped grate. Fig. 3 is a sectional view of `the device at right angles to that shown in Fig. 1. Fig. 4 is a plan View of the ladlesupporting grate beneath the tap-hole, and Fig. 5 is a sectional view of said grate at 'line x :c of Fig. 4.

Like letters of reference, wherever they oc- 7o cur, indicate corresponding parts in all the figures. Y

1. In a cupola, a cone-shaped grate located beneath the furnace, and adapted and arranged'to receive the dump, holding it in an elevated position while the molten metal drains therefrom, substantially as shown and described.

2. In a cupola-furnace, a cone-shaped grate located beneath the hinged bottom, said grate being mounted upon wheels traveling upon a supporting-track, substantially as shown and described. A
